I think people on the board are confused and inconsistent.

Mostly people demonise and hate mixed race most of the time and almost appear unanimous that mixed isn't black because of the very one-drop rule you mention... but when it comes to the idea of mixed people having their own race categorys and sites or things of their own... everybody throws hissy fits as if they're traitors and it won't be good for black folk. When mixed folk date white blacks here act shocked lol or call them traitors even. Traitors to whom?

I do not agree that biracial people are black. They are no more so than they are white and one drop rule upholds the notion that white is pure and everything else is contaminated black...I don't subscribe. Why is Mariah or people as white as her with visible blue veins even near considered "black". Have we gone blind? Also from experience people raised by white parents have a white idealogical background and thinking that is vastly at odds with most black people. To deny this is determined willful ignorance imo. We know that mixed couples don't last and we know that it's usually black men with white women vastly outnumbering the reverse so effectively it's white women bring up the majority of mixed kids alone. Kids who some argue are "black". Bollox

A biracial or mixed race person is precisely that. And that's not black. The sooner we realise this and move on the better. For them in the most part but for us too.
